Answer:

A) (3x + 21)(x + 7)

Step-by-step explanation:

If we look at the equation we can see that it is a quadratic equation, therefore we can factor it in the following way...

$3x^{2} + 42x + 147 = 3x^{2} + 21x + 21x + 147 = 3x(x + 7) + 21(x + 7) = (3x + 21)(x + 7)$

Therefore the answer is A)

Answer and how to solve this

Step-by-step explanation:

When it says x = something, that basically means to replace the x with whatever it says x equals.

x = 0. Equation /. 3 x 0 = 0 + 1 = 1. Y = 1

x = -1. Equation/. 3 x -1 = -3 + 1 = -2. Y = -2

x = 2. Equation/. 3 x 2 = 6 + 1 = 7. Y = 7

Hope this helps!! (:

Answer:

The answer to your question is: ( - 24 / 29, ∞ )

Step-by-step explanation:

6x + 3 < 8 (8x + 6) + 3

6x + 3 < 64x + 48 + 3

6x + 3 < 64x + 51

6x - 64x < 51 - 3

- 58 x < 48

x > - 48 / 58

x > - 24 / 29

( - 24 / 29, ∞ )
